Hold'em table

ATo on the button is a strong enough open to raise for value and take initiative preflop; raising to 3bb is standard.

Q2 offsuit is too weak to defend from the small blind against a 3bb button raise, especially with the big blind still to act. Folding avoids investing further with poor equity realization out of position.

2-6 offsuit is a weak hand facing a raise; folding is correct even with low cost since equity and hand strength are poor.

Nine-six offsuit is too weak for a standard button open at 100bb without evidence that the blinds overfold. Folding avoids investing in a hand with poor playability.

AK is a premium hand heads-up against the big blind; raising to build the pot and isolate.

T5o is too weak to call a raise out of position, especially with poor postflop playability.

K2 offsuit from the button facing a raise-limp situation isn't strong enough to invest chips; fold and wait for a better spot.

Getting 3:1 with J5o after the button folds; calling 50 is cheap, while raising would build a pot out of position with a weak hand.

With 64 offsuit against a small-blind limp, taking a free flop in position is preferable to building a pot with a weak hand.

I have middle pair on a coordinated board and am first to act; checking controls the pot and avoids getting raised by stronger hands.

I have no pair, useful draw, or relevant blockers on this connected board. Checking preserves chips rather than bluffing into a range that can readily connect with it.

Middle pair with a weak kicker on a very coordinated board; checking controls the pot and avoids getting raised by straights or better pairs.

With almost no showdown value, I can profitably pressure a small blind who has checked twice. A three-quarter-pot bluff targets unpaired hands and weak pairs while risking relatively little.

I have middle pair with a gutshot and am getting 350-to-150 pot odds, so calling is reasonable against a possible turn stab. Raising would risk too much with a marginal hand and no diamond.

I have two pair (jacks and fives), but the board is coordinated and opponent raised the turn, so checking controls the pot and avoids bloating it against a likely stronger range.

Six-high has essentially no showdown value, while the opponent can have missed diamond or straight draws after calling the turn. A three-quarter-pot bluff continues the turn aggression and pressures missed draws and weaker pairs.

I have two pair (jacks and fives) and am getting 2.33:1 pot odds. Opponent could be value betting worse or bluffing, so calling is profitable.

T5o is too weak to continue from the button against two blinds, even with position; folding avoids playing a dominated offsuit hand out of flow.

With the button folded, A2 offsuit is strong enough to open small blind versus big blind. Raising to 3bb pressures the big blind's wide range and can win the pot immediately.

K6o offsuit is weak against a raise with a 3bb reraise price; folding is cheap and preserves chips.

J5 offsuit is too weak for a profitable default button open against two unknown blinds. Folding avoids investing in a hand with poor connectivity and frequent domination.

Heads-up against the big blind with an ace-high hand, a small raise to build the pot and apply pressure is profitable.

Getting 2:1 pot odds with a suited connector against a likely small-blind steal, so calling is profitable enough and keeps the pot manageable out of position.

I missed completely with just ace-high on a very coordinated board against two opponents, so I'll check and look to see a free card rather than bluff into likely strength.

I have an open-ended straight draw and position; betting can take the pot down or build it with strong equity.

Only an ace-high gutshot draw against a bet on a coordinated K-Q-J board; equity doesn't meet the required pot odds, so folding is correct.

KQo is a strong button hand; raising to 2.5x builds the pot and leverages position against two limpers/blinds.

94o is too weak to defend out of position against a button raise, so folding preserves chips.

Pocket eights is a strong defend against a button open, and calling costs only 150 into a 400-chip pot. Calling preserves the opponent's weaker hands without inflating the pot out of position.

Checking keeps the button's weaker hands and bluffs in while protecting my checking range. My overpair has solid showdown value, but it is not strong enough to build a large pot indiscriminately on this coordinated board.

As preflop raiser I should c-bet this dry board with overcards and a backdoor flush draw to take down the pot or build equity.

Our overpair is strong enough to continue against a button continuation bet, with backdoor straight and flush potential. Calling keeps weaker hands and bluffs in while avoiding inflating the pot against stronger overpairs and sets.

Checking preserves showdown value with a pair of eights and a modest club redraw. Leading into the preflop raiser on this turn risks building a pot against stronger pairs and flushes while folding out weaker hands.

I hold a strong flush draw (Qc) with two overcards to the board; betting here applies pressure and gives me good equity if called, especially against a passive check from the big blind.

Pocket eights still beat unpaired barrels, and the club adds some backup equity against one-pair value hands. Getting about 2.5-to-1, I can defend this combination without inflating the pot with a raise.

Pocket eights retain showdown value against missed draws and unpaired overcards, but betting is unlikely to get called by worse. Checking keeps the pot controlled and preserves the option to assess a river bet.

I missed completely with king-high and no made hand; villain called two streets so a bluff is unlikely to work, so I check and give up the pot.
